" '4 2 c1ai1p's.l. (o1.l '6c-iss) mThis invention relates to an'improved method of forming 'fabric wherein the usual knitv fabric is presented, and in addition ornamental protuberances at desired points. l

An additional object of the invention is to provide an improved method of forming a knitted fabric wherein the knitted body of the usual type is presented and at the same time folded over portions are provided to give different ornamental effects.`

In the accompanying jdrawingl Figure l is a fragmentaryfview showing one needle of `a 'circular knitting machine with part of a piece of the fabric associated therewith;

Figure 2 shows the arrangement of the needle and fabric as illustrated in Figure l, and in addition certain other mechanism of a knitting machine for producing a foldedover condition of the fabric;

Figure 8 is a plan view of a piece of fabric constructed according to the present invention.

Referring to the accompanying drawing by numerals, I indicates a piece of fabric Ywhich is knitted on a well known circular machine, the body of the fabric being of the usual knit structure now well known. However, at desired points there are provided folds or protuberances 2 which are formed according to the present invention.

v In forming the members 2 a portion 3 of the fabric l5 as shown in Figure 6 is folded over and then the ,Various needles 4 are caused to pass through this v folded over portion while in folded over position Vwheel I1. ymines the length of the section 3 or the pro- .ure 8 lwith protuberanoes 2 scattered over the fabric butinregular order. l

In knitting thefabric I the same is knit on a circular knitting machine now incomrnonA use provided with a number of 'needles 4, as shown in Figures 1 to 7, and thefabric I, extends upwardly from thev needles. This fabric kept under' some desirable tension. After a certain amount of the fabric has been knitted and it is desired to produce one of the protuberances 2, the Wheel 5 is lo caused to hold the fabric as shown in Figure 2. The auxiliary cam 8 is new and coacts with the wheel 5 which is also new, so as to force the fabric into position 9. As the fabric leavesthe wheel 6 and cam 8 a second new wheel It) comes into use and engages the fabricV I forcing the same downwardly as shown in Figure 3,-whereby the portion 9 will remain substantially in its original position, but the loop I I will be projected. It will be noticed that the loop I I and portion 9 and 2O the parts engaged by wheel ID are all knit completely, and consequently when these parts are forced downwardly the needles 4 protrude through the complete fabric as shown in Figure 6.

As shown inv Figure 7 the wheel I0 is spaced a short distance from wheel I0', which latter wheel is old and in common use. It will be understood that the fabric I and the needles 4 all rotate at the same speed, so that when the fabric Y leaves wheel I0 it begins to be moved upwardly, and all the fabric will move kupwardly except '3u those portions opposite the open `space I6 on 'Ihe size of the open space I6 detertuberance 2. As the fabric passes the wheel I6 the part which is still protruding, namely, part 3, will be held down by wheel I0', and immediately before the parts leave wheel IB the yarn 5 will be caught by theneedles 4 during the regular knitting operation as the wheel I8 functions, said wheel I8 being old and well known. As the parts leave the wheel III the cam I2 closes the eyes of the needles so that after the yarn 5 has been positioned as shown in Figure 4, lthe fabric may be pulled upwardly as indicated by the arrow I3.

When in its extreme upper position there is presented a small loop I 4 which is the same as the portion 3 or the protuberance 2 except that it is on an enlarged scale. This loop does not remain in its position but is attened down by reason of the tension on the parts, so that it looks like a short ridge, as indicated in Figure 2. AThe machine then continues to complete the fabric in the usual way so as to form the body I5. It *55 wm therefore be seen that in forming the fabric 1, the bodyV is-knit in the usual manner and at certain intervals mechanism pushes down small batches of the knit fabric over certain of the needles and then a yarn is knit into these batches so as to hold them permanently in place. In this vwayvwhen a yarn is knitted into thesebatches or looped over portions, a construction is presented f at the'bases of the looped over portions which `will act as a. retainingyseamto hold the parts in f fabric is knit throughout and the protuberances are formed before the fabric-leavesjthe `nfiaclriiire*V but after the fabric has been knit. IizgwillyheA evident that a large folded portion or a. Small folded over portion may be provided asvshown in Figure. ewithout departing from'thespirit of the invention. Y* 'i j As` indicated in Figure 7 there is one complete group which is` adapted at certain interval'stifp` form a protuberance 2. In many machines there would be a large number of these groupsas, for

instance, ten groups to one machine, and conse- 'y quently there would be as manyprotuberances 2 for eachk revolution as there are groups. It is evident that a larger or smaller number might be used Without departing from the spirit of the' invention, and the protuberances could be spaced Y Y closer together or further apart,

I claim: V- Y l. The method of forming a fabric having a knit body and a number of ornamental protuvberances thereon, consisting in knitting 'said body for a certainfdistance, looping short sections of said knit body over certain of the needles of Ythe knitting machine, knitting a yarn through the base of saidlooped over portions,V andV then knit ting said body 1n the regular manner.v

c v-2. Thermethod ofrforming a knit fabric, com
